There is no Action mapped for namespace [/] and action name [] associated with context path [duplicate]

Answer 1

I was also getting similar error. The resolution was that "struts.xml" file was in "web" folder.

It MUST be in the "src" source folder.

Make the change and restart the server.

Answer 2

I was also getting the same error. Solved the issue by relocating the struts.xml location to the root directory of src folder in eclipse project

Answer 3

Thanks to all. I changed my struts.xml as below correcting the errors mentioned and the naming convention and was able to solve the issue.

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<constant name="struts.devMode" value="true" />

<package name="user" namespace="/User" extends="struts-default">
    <action name="login">
        <result>pages/HomePage.jsp</result>
    </action>

    <action name="ValidateLogin" class="com.user.struts.ValidateLogin" method="execute">
        <result name="SUCCESS">pages/Success.jsp</result>
        <result name="FAILURE">pages/Failure.jsp</result>
    </action>

</package>  
</struts>

I don't know if anyone still has this problem but this is what i did-

change your package name in "helloaction.java" class

Most of the people, including me just write how a tutorial shows so after hours of debugging i finally got the problem.

package com.tutorialspoint.struts2;

I had written the above line in my action(.java) class. which made a package "com.tutorialspoint" in src folder. But the syntax actually means there is a package tutorialspoint inside com package. So what basically the tutorial had was

src->com->tutorialspoint->helloaction.java

So after getting no solution from all the search i changed the name of my package to "practice" in both .java class & struts.xml and it worked fine.

src->practice->helloaction.java

Hopefully if anyone was doing the same mistake like me...it helped. It may not be the solution but it worked for me when everything else didn't.

Answer 5

First learn how to specify a class in struts.xml

class="/LoginApplication/src/ValidateLogin" is wrong way to specify

<action name="validatelogin" class="/LoginApplication/src/ValidateLogin" <- this is wrong 
  method="execute">
     <result name="Success">/Pages/Success.jsp</result>
     <result name="Failure">/Pages/Failure.jsp</result>
</action>

You should correct it and write class="ValidateLogin" if the file name is ValidateLogin.java

If the java class file is in some package then it should be

class="yourPackageName.ValidateLogin"

Answer 6

By default, the program will find index.jsp.
If you don't have index.jsp in your [/] directory, that error will happen.
Or you have to choose another file in web.xml

Solution:
In your web.xml add this code under filter-mapping

<welcome-file-list>
        <welcome-file>/Pages/HomePage.jsp</welcome-file>
</welcome-file-list>
